GAS-ENGIN ,E COOLER.

SPECIFICATION forming part of Letters Iatent No. 755,399, dated March22,1904.

Application flied June30,1903. Beria1No.163,723. (NomodaL) To all whomit may concern.-

Be it known that I, CHARLES E. SHAMBAUGH, a citizen of the UnitedStates, and a resident of Lafayette, in the county ofTippecanoe-andState of Indiana, have made certain new and useful Improvements inGas-Engine Coolers, of which the following is a specification.

My invention relates to gas-engine coolers, more definitely stated,improved means whereby increased radiation of heat is effected.

The invention consists in the special construction, arrangement, andcombination of parts, which will hereinafter be fully described and thenovel features pointed out in the subjoined claims.

In order to enable others to make and use my invention, I will nowproceed to describe it in detail, with reference to the accompany: ingdrawings, which form part of this specifi cation. I

In the drawings, Figure 1 is a longitudinal sectional view taken on line1 1 of Fig. 2. Fig. 2 is a transverse sectional view, taken on line 2 2of Fig. 1. Fig. 3 is an enlarged detail view illustrating the ribprojections.

In practicing my invention I employ a series of elongated plates A,extending substantially the whole'length of the engine-cylinder and withthe plates arranged in radial position, as will be fully understood byreference to Figs. 1 and 2 of my drawings. A special feature of myinvention in connection with 'the elongated and radially-arranged platesis phiyrd' whereby increased rad1 .d with minimum pro ection the meansc"of the plat as.

The radiating-plates A are adapted for the increased or improvedradiation above mentioned by having lengthwise grooves a and ribs 12 ontheir opposite sides, the ribs 6 being provided transversely of theplate witha series of chiselecuts c, forming projections (2. Obviouslythe projections (1 may be formed by other means than chisel-cuts, themain idea being roughening of the" said ribs to afford increasedradiating-surface, and therefore I do not desire to be limited to anyparticular form. of projection d in the series thereof or means wherebythey are formed. The flanges A may be secured to the cylinder B byhaving their side edges fixedly seated in'snitable grooves C in thecylinder, as shown in Fig. 2

Having thus fully described my invention,-

what I claim is I 1. The combination with an engine-cylinder, ofradially disposed plates grooved lengthwise thereof on opposite sides,ribs between the grooves having series of transverse pro jections,substantially as described.

2. The combination with an engine-cylinder, of radially-disposed platesseated in longitudinally-arranged grooves in the cylinder, the saidplates being grooved lengthwisethereof on opposite sides, the ribs.between the grooves having series of'transverse projections formed bystruck-up portions, substantially as described.
